Anyone has experience with scanControl


Recommended Posts

Hi,

I am working on a project which using scanControl to scan the  D surface of products to detect engraved serial number by laser. I have never used this laser sensor before. I have not had much successful to read back an image with clear. The result I got is hard to process. I think maybe I did not get the correct data I want. I wonder if there is someone familiar with communication interface with this device can share me the sequence of functions using to get an intensity image of 3D surface.

 

Thank you!

Is this device from MicroEpsilon? there is an instrument driver for it in LabVIEW i think:

 

The scanCONTROL LabVIEW instrument driver

supports the rapid integration of the profile sensors

in the National Instruments’ LabVIEW®

programming environment. Access to scan-

CONTROL sensors and their basic settings is

depicted in individual modules that can be directly

integrated in your own VIs using the software

functions. Example VIs also form part of

the integration process.

The integration of scanCONTROL sensors

in the LabVIEW programming environment

is based on the C/C++ library “LLT.dll” from

Micro-Epsilon. The extensive documentation

explains how its additional special sensor parameters

can be set up.

- Meets the National Instruments guidelines

for LabVIEW instrument drivers

- Supports LabVIEW 8.6 and higher

- Easy access to a range of functions via

function palette

- Support for the FireWire and Ethernet

interface

- Example VIs, inc. single profile transfer and

container mode

Software for scanner integration

The examples contained in the SDK also

demonstrate how the different interfaces (serial,

FireWire, and Ethernet) can be effectively

configured

anh Minh,

I have a problem with the white area on the top right of the character which make the algorithm cannot work correctly. That is created with the pump up of the surface of the device. It will go away if I scan along the length of the text but requirement is I have to be able to scan both ways, along the height of the text and along the length of the text. Do you have any experience with this?
